Thanks @ptlrs for working on this.
Do you think we should create a "quickstart" branch for this image so that it can live separately?
It definitely needs a separate branch, but I'd prefer all-in-one as Docker tag, hence ozone-all-in-one as branch name.

apache/ozone-quickstart repository does not exist, but this build.sh is only for developers' local build, so it can use any tag.

To simplify things, we can add these as actual config files (ozone-site.xml, core-site.xml, etc.) instead of environment variables.

Can this be done in Dockerfile instead?

I think only S3 Gateway and Recon ports should be included in this quickstart.

This all-in-one config has a single datanode. Default replication 3 is setting up for failure.

apache/ozone-quickstart does not exist. I'd prefer to tag this image as all-in-one, so this would be apache/ozone:all-in-one.

OZONE_RUNNER_IMAGE is overridden by GitHub Actions workflow with ghcr.io/apache/ozone-runner (to use GitHub-local base image in CI), so this won't work.
Please rename the variables to OZONE_IMAGE and OZONE_IMAGE_VERSION here, in build.sh and in .github/workflows/build.yaml.

EXPOSE is not functional, just documentation. Since this is for quickstart, I don't think we should expose internal ports like Datanode, OM, SCM.

I think this doc should replace README.md (and consider removing or updating CONTRIBUTING.md on this branch).

Created a docker image based off of the slim Ozone image.
This image will provide a single container with all ozone components up and running.
This will be useful for quick POCs with Ozone.
